OTG Timers Customizing It is possible to refine some OTG timers thanks to the OTGTCON register (see
Table 108). This register is multiplexed with the OTGCON register. The timers are as
defined in the OTG specification:
AWaitVrise time-out. [OTG] chapter 6.6.5.1
VbBusPulsing. [OTG] chapter 5.3.4
PdTmOutCnt. [OTG] chapter 5.3.2
SRPDetTmOut. [OTG] chapter 5.3.3
Table 101. OTG Timer Configuration
Plug-in detection
The USB connection is detected by the VBUS pad, thanks to the following architecture:
